This paper discusses the preliminary development of a neural network-based process monitor and off-line controller for abrasive flow machining of automotive engine intake manifolds. The process is only observable indirectly, yet the time at which machining achieves the specified air flow rate must be estimated accurately. A neural network model is used to estimate when the process has achieved ...

The titanium alloy artificial knee joint is used extensively in the current medical industry due to its distinct characteristics and properties that are like real human joint, but it does need be polished improve performance service life before can used. Due complicated surface profile, traditional abrasive flow machining technique cannot achieve a good finish offering uniformity quality. Thus,...

OBJECTIVE The aim of this retrospective study was to analyze collected data concerning the effect of an air-abrasive device (Perio-Flow®) during surgical treatment of peri-implantitis without addition of any antimicrobials. METHOD AND MATERIALS Data reports from 22 implants with peri-implantitis surgically treated using either an air-abrasive device (Perio- Flow) (test group), or plastic cure...

A new polishing process for metallic parts has been developed by simultaneously coupling drag finishing and electrochemical polishing. This hybrid process, called PEMEC, enables an improvement in the surface roughness within some minutes, at same time, preserves shape of edges. is based on a synergistic effect between abrasive chemical mechanisms. It confirmed its suitability to be applied comp...
